I just bought a Pro-pointer, and today was my First chance to really use it! What a time saver!
I found these in the back yard, nothing special, the neatest to me is the old square nail.
I decided to stick to my backyard until I began to know what my detector was "telling" me. I pretty much flip between modes...beginning with all-metal then flipping to tone...and ultimately digging it up anyway. What I can tell is it isn't as simple as material/tone. Depth, orientation...
